76. The first time aero bars appeared in the Tour, in 1989, they snatched the yellow jersey away from Laurent Fignon by helping Greg LeMond overcome a 50-second deficit in the final stage. It was LeMond's second win. In 1986, he became the first American to wear the yellow jersey and also to win the Tour.

77. In the 1991 Tour, Danish rider Rolf Sorensen crashed out of the Tour while wearing the yellow jersey.

78. The current practice is to give the rider in yellow two jerseys after the podium ceremony. If cold weather is forecast the following day, the rider can ask for one of the two to be long-sleeved.

79. Prices for a yellow jersey depend on if the garment was actually worn in the race. When sold to fund his foundation for cancer survivors, an unused Lance Armstrong yellow jersey can fetch upwards of $25,000; one worn in the race is about double. Current value of an Eddy Merckx yellow jersey: about $10,000.

80. Eight riders wore the yellow jersey in the 1987 Tour. The most exciting battle for it came on the road to La Plagne in the Alps, with Spaniard Pedro Delgado in yellow. At the base of the final, 11-mile climb, Delgado was three minutes ahead of his main rival, Stephen Roche, who appeared to be bonking. Somehow, with only 2.5 miles remaining, Roche dug deep into himself. As Delgado crossed the line, Roche appeared around the last corner, only 20 seconds back. He collapsed at the finish, was put on oxygen and taken by ambulance to a hospital for the night. The plucky Irishman reappeared at the start the next day, won the final individual time trial a few days later, and claimed his country's first, and only, overall yellow jersey in Paris.

81. In 1985, Bernard Hinault won his fifth overall yellow jersey largely thanks to the aid of his American teammate, Greg LeMond. LeMond was probably strong enough to win that year, but gave up his shot in return for a promise that Hinault would repay the favor next year. But in the first stage of the Pyrenees in 1986, Hinault launched a surprise attack and gained five minutes over LeMond. Popular opinion said the Tour was over, and Hinault was on track for jersey number six. But the inscrutable Hinault attacked again the next day in the Pyrenees and blew up. LeMond closed, won the stage and erased Hinault's lead, then secured the jersey for good in the Alps.
